In a galvanic corrosion setting, a graded material can expose a variety of corrosion potentials to an electrolyte whereas a monolithic material presents only one. The corrosion performance of such graded materials is complex and collaborative, and the concept opens a broad and highly nonlinear design space for new galvanic coatings with large potential performance benefits. This talk will present a new computational modeling and optimization paradigm for the design of next generation galvanic coatings. The combination of a variety of computational tools will be described; this includes conventional electrochemical continuum modeling, as well as new approaches to localized corrosion modeling via effective medium theory, and the introduction of optimization algorithms for rigorous coating design. The predictions of these methods will be shown to reproduce critical experimental results, and also to guide the development of new coating architectures with improved corrosion performance.
